Cybersecurity researchers have discovered a critical security flaw in an artificial intelligence (AI)-as-a-service provider  Replicate  that could have allowed threat actors to gain access to proprietary AI models and sensitive information. "Exploitation of this vulnerability would have allowed unauthorized access to the AI prompts and results of all Replicate's platform customers," cloud security firm Wiz  said  in a report published this week. The issue stems from the fact that AI models are typically packaged in formats that allow arbitrary code execution, which an attacker could weaponize to perform cross-tenant attacks by means of a malicious model. Replicate makes use of an open-source tool called  Cog  to containerize and package machine learning models that could then be deployed either in a self-hosted environment or to Replicate. Wiz said that it created a rogue Cog container and uploaded it to Replicate, ultimately employing it to...

The MITRE Corporation has revealed that the cyber attack targeting the not-for-profit company towards late December 2023 by exploiting zero-day flaws in Ivanti Connect Secure (ICS) involved the threat actor creating rogue virtual machines (VMs) within its VMware environment. "The adversary created their own rogue VMs within the VMware environment, leveraging compromised vCenter Server access," MITRE researchers Lex Crumpton and Charles Clancy  said . "They wrote and deployed a JSP web shell (BEEFLUSH) under the vCenter Server's Tomcat server to execute a Python-based tunneling tool, facilitating SSH connections between adversary-created VMs and the ESXi hypervisor infrastructure." The motive behind such a move is to sidestep detection by obscuring their malicious activities from centralized management interfaces like vCenter and maintain persistent access while reducing the risk of being discovered. Details of the attack  emerged  last month when MITRE rev...

Threat actors have been observed making use of fake websites masquerading as legitimate antivirus solutions from Avast, Bitdefender, and Malwarebytes to propagate malware capable of stealing sensitive information from Android and Windows devices. "Hosting malicious software through sites which look legitimate is predatory to general consumers, especially those who look to protect their devices from cyber attacks," Trellix security researcher Gurumoorthi Ramanathan  said . The list of websites is below - avast-securedownload[.]com, which is used to deliver the  SpyNote trojan  in the form of an Android package file ("Avast.apk") that, once installed, requests for intrusive permissions to read SMS messages and call logs, install and delete apps, take screenshot, track location, and even mine cryptocurrency bitdefender-app[.]com, which is used to deliver a ZIP archive file ("setup-win-x86-x64.exe.zip") that deploys the  Lumma  information stealer malw...

Don't be fooled into thinking that cyber threats are only a problem for large organizations.

Introduction The Colonial Pipeline ransomware attack (2021) and SolarWinds supply chain attack (2020) were pivotal moments in cybersecurity, starting a new challenge for Chief Information Security Officers ( CISOs ). These attacks highlighted the importance of collaboration between CISOs and DevOps teams to ensure proper cloud security configurations. In this article, we will outline the 6-step approach to fostering strong partnerships between CISOs, DevOps teams, IT management, and organizations that can help to drive innovation while maintaining a robust security posture. You will learn how a CISO can effectively communicate with IT leadership and what methods to try. Our narrative will emphasize the most crucial aspect of an organization's security - growing your strong security team and moving to a proactive approach.  Understanding such breaches, such as the Capital One data breach (2019), Epsilon data breach (2019), Magecart compromises (ongoing), and MongoDB breaches (2...

Google on Thursday rolled out fixes to address a high-severity security flaw in its Chrome browser that it said has been exploited in the wild. Assigned the CVE identifier  CVE-2024-5274 , the vulnerability relates to a type confusion bug in the V8 JavaScript and WebAssembly engine. It was reported by Clément Lecigne of Google's Threat Analysis Group and Brendon Tiszka of Chrome Security on May 20, 2024. Type confusion vulnerabilities  occur when a program attempts to access a resource with an incompatible type. It can have  serious consequences  as it allows threat actors to perform out-of-bounds memory access, cause a crash, and execute arbitrary code. The development marks the fourth zero-day that Google has patched since the start of the month after  CVE-2024-4671 ,  CVE-2024-4761 , and  CVE-2024-4947 . The tech giant did not disclose additional technical details about the flaw, but  acknowled...

Malicious actors have backdoored the installer associated with courtroom video recording software developed by Justice AV Solutions (JAVS) to deliver malware that's associated with a known implant called RustDoor. The software supply chain attack, tracked as CVE-2024-4978 (CVSS score: 8.7), impacts JAVS Viewer v8.3.7, a component of the  JAVS Suite 8  that allows users to create, manage, publish, and view digital recordings of courtroom proceedings, business meetings, and city council sessions. Cybersecurity firm Rapid7  said  it commenced an investigation earlier this month after discovering a malicious executable called "fffmpeg.exe" (note the three Fs) in the Windows installation folder of the software, tracing it to a binary named "JAVS Viewer Setup 8.3.7.250-1.exe" that was downloaded from the official JAVS site on March 5, 2024. "Analysis of the installer JAVS Viewer Setup 8.3.7.250-1.exe showed that it was signed with an unexpected Authenticode ...

Cybersecurity researchers have discovered that the malware known as  BLOODALCHEMY  used in attacks targeting government organizations in Southern and Southeastern Asia is in fact an updated version of Deed RAT, which is believed to be a successor to ShadowPad. "The origin of BLOODALCHEMY and Deed RAT is ShadowPad and given the history of ShadowPad being utilized in numerous APT campaigns, it is crucial to pay special attention to the usage trend of this malware," Japanese company ITOCHU Cyber & Intelligence  said . BLOODALCHEMY was  first documented  by Elastic Security Labs in October 2023 in connection with a campaign mounted by an intrusion set it tracks as REF5961 targeting the Association of Southeast Asian Nations (ASEAN) countries. A barebones x86 backdoor written in C, it's injected into a signed benign process ("BrDifxapi.exe") using a technique called DLL side-loading, and is capable of overwriting the toolset, gathering ho...

Ransomware attacks targeting VMware ESXi infrastructure follow an established pattern regardless of the file-encrypting malware deployed, new findings show. "Virtualization platforms are a core component of organizational IT infrastructure, yet they often suffer from inherent misconfigurations and vulnerabilities, making them a lucrative and highly effective target for threat actors to abuse," cybersecurity firm Sygnia  said  in a report shared with The Hacker News. The Israeli company, through its incident response efforts involving various ransomware families like LockBit, HelloKitty, BlackMatter, RedAlert (N13V), Scattered Spider, Akira, Cactus, BlackCat and Cheerscrypt, found that attacks on virtualization environments adhere to a similar sequence of actions. This includes the following steps - Obtaining initial access through phishing attacks, malicious file downloads, and exploitation of known vulnerabilities in internet-facing assets Escalating their ...
